Application filed June 8, 1912. Serial No. 702,466.

'1'0 all whom it may concern:

Be it known that we, ROLLIN H. WHITE and CLARENCE G. Wnrrn, citizens of the United States, and residents, respectively, of Cleveland, in the county of Cuyahoga and.

.State of ()hio, and Haiku, in the county of Maui and Territory of Hawaii, have invented a certain new and useful. Improvement in Power-Propelled Agricultural Machinery, of which the following is a full, clear, and exact description.

This invention relates to power propelled agricultural machh'iery.

The object is to provide a self propelled traction machine and to equip this traction machine with devices which are designed to engage with the soil to plow or harrow the same.

The engine employed to furnish power is preferably of the motor vehicle type, and the machine is provided with devices to effect various speeds of the driven members.

With this object in mind, the invention may he said to romprise the elements and con'ibinations thcrcoi set forth in the accompanying claims.

Reference should be had to the accompanying drawings forming a rart of this application in which Figure 1 1s a tide elevarion of the machine; Fig. 3 is a view of the machine; Fig. 3 is a top plan view of the rear portion of the machine, with portions of the apparatus removed; Fig. 4.- is an end elevation with arts in section of that part of the machine carrying the disks and driving connections for the disks; Fig. 5 is a sectional elevation upon the line 5-5 of Fig. 2.

A machine constructed in accordance with this invention comprises a chassis having side pieces 1 and 2 which are suitably joined together at various points throughout their There is also an auxiliary frame or chassis which comprises side pieces 4 and 5. These are bent in the manner represented in Fig. 1 and are so arranged that portions 4 and 5 extend below and are substantially parallel with the side pieces 1 and 2 of the main chassis. Upon the portions of the auxiliary frame 4* and 5 there is mounted a shaft 6 which is suitably jourualed upon. and extends bctwecn the same.

Upon -this shaft is mounted a two-part up plan traction roller, the parts of the roller being designated at 7 and 8 respectively. Behind the traction roller there is mounted upon the auxiliary frame a transverse shaft consistin of the parts 9 and 10 which are joined together by a. difl'erential mechanism contained within the casing 11. The shafts 9 and 10 carry at their outer portions gear wheels 12 and 12.

There are also gear wheels 13 and 14 carried by the portions 8 and of the traction. drum. The sprockets 12 and 13 and the sprockets 12 and 1-1 are suitably connected by a chain so that motion may be trans mitted from the shafts 9 and 10 to the pertions 7 and 8 of the traction roller.

The differential mechanism connecting tlfe shafts -9 and 10, may be of usual construction. Its function is the usual one, viz: to

crmit the shafts 9 and 10 to rotate at diferent speeds under certain conditions which of course, permits the two parts 7 and 8 0 the traction roller to do the same.

At the. forward part of the chassis there is mounted an engine 1.5 which may be of any desired type and is designed to furnish power to drive the various instrumentalities which are associated with. this machine. The engine is protected'by a hood 16 of usual construction. which is provided with a. radiator 17.

The crank shaft of the engine is as usual equipped with awfiy wheel 18, which by suitable clutch mechanism is operatively connectcd with a shaft 19. This shaft extends into a transmission casing 20, which easing contains the usual mechanism. for changing the speed and for reversing the direction of travel of the machine.

The driven shaft emerging; from the casing 20 is indicated" at 21 and this shaft is provided with a sprocket wheel 22 which is in alinement with a. sproc (ct wheel 23. The sprocket wheel 23 is carriedlby theshaft 24 which extends within the housing 11 and is the driving shaft for the.difl'erential mechanism contained within the housing 11. The sprocket wheels 2-2 and 23. are connected by a sprocket chain. which completes the necessary connections betweltn'thoengine 15 and the port ions 7 and 8 of the traction roller so that the same may be driven.

1 Upon the side pieces 1 and 2 of the chassis toward the real-portion thereof there is secured a member 25, which we may describe as the pivot for a turn-table. This member is are shaped or circular throughout the greater portion of its peripheral extent. The member 25 is formed with oppositely projecting flanges at the top and bottom thereof;

Cooperating with the member 25 is a member 26 which is of substantially the same configuration as the member 25 and also is formed with oppositely projecting flanges at the top and bottom. The upper flanged portion of the member 26 is secured against the lower flanged portion of the member 25 by means of an L-shaped ring member 27 which engages beneath the upper flange or extension upon the member 26. This L- shaped ring 27 is held upon the member 25 by means of bolts, such as represented at 28, which bolts cotiperate with the upper flange of the member 25. It will readily be seen from the construction described that the members 25 and 26 may move relatively to each other, sliding upon their contacting flan es.

T e member 26 is provided with arms 29 which extend toward the center of the member and join in a central body or hub 30. This hub has a downwardly projecting stub axle 31.

As before mentioned, the member 26 is substantially circular throughout the greater portion of its length. However, a portion of this member represented at 26 in Fig. 3 is substantially straight, and to this member 26 there is secured a cross member 32 which is substantially straight. To the ppposite ends of the cross member 32 there is secured the opposite ends of a circular member 33. The member 33 is also joined to the circular portion of the member 26 by bracing pieces 34 and 35, as suggested in Fig. 3. It will thus be seen that the member 26, with the member 32 and 33 forms a rigid structure or turn table which may move upon the member 25, acting as a pivot.

Carried by the rigid structure or turn table just mentioned are frames generally represented at 36 and 37 ,Which frames comprise side pieces 38 and 39, and end pieces 4.0 and 41. The end pieces 40 are provided with extensions 42 and 43 having openings thcrethrough-which engage with the stub axle 31 before mentioned, and these extensions 42 and 43 are held in place by a nut 44. The frames 36 and 37 're secured to the members 26 and 33 respertively. Any desired form of connection may be used, but T have shown for the purpose L-shaped bolts representedat45 and 46.

Toward the outer portion of each frame i and 37 there is a cross brace 47 having an opening through which extends a sleeve 48, the sleev being secured in the opening. Through die, sleeve there extends a shaft 49,

the shaft at its lower end supporting a jour nal in which is mounted a hub or spool which spaces apart the disks, as will later be described.

Near their inner ends the side members of the frames are joined by standards 50, these standards being more completely shown in Fig. 5.

The standards are preferably formed as a unitary structure, the lower part or base of the structure being joined to the opposite sides of the frames 36 and 37. The sides of the standards are slanting and the central part is open. Each standard in the lower part or base thereof is formed with an enlarged hollow portion generally represented at 51, in which is journaled a sleeve 52.

At the lower portion of the sleeve there is a yoke 53 which supports a journal adapted to engage one of the hubs or spools which s ace apart the disks.

The s eeve 52 is formed with a rack 54, and the shaft '49 is formed with a rack 49". These racks 49 and 54 engage with pinions 55 and 56, which pinions are both upon a shaft 57. The shaft is journaled in the cross member 47 and the base of the standard 50. The shaft extends sli htly beyond the base of the standard 50 am? on the extending ortion of each shaft there is a wheel 58 which is operated in a manner later to be described, and by the turning of which, the pinions engaging with the racks 49 and 54 may be operated so as to raise and lower the shaft 49 and the sleeve 52, thereby raising and lowerin the disks.

The isks 59 are in the main of usual construction and are mounted upon a squared shaft 60. These disks are provided with square openings which fit upon the squared shafts 60 and are spaced apart by means of spools or hubs 61. As before stated, one of these spools is mounted in a journal carried by the lower part of the shaft 49, and another is mounted in a journal carried by the lower part of the sleeve 52. This permits of the rotation of the shaft, spools and disks.

Extending through each sleeve 52 is a shaft 62. which at its lower end is journaled in a portion of the yoke 53. Upon this shaft is a gear wheel 63, the same being provided with teeth. These teeth are adapted to extend into openings 64 formed in a disk 59, which is adjacent to the gear wheel 63. As shown in Fig. 5, the openings 64 extend'in an annular series, and it will therefore be apparent that rotation of the gear 63 results in rotating the disk 59 in which the openings are formed. and inasmuch as the disks 59 are all rigidly secured to the shaft 60, the driving of the one disk results in driving all the disks or gang of disks. as they are called, associated with the shaft 60.

There are two such gangs of disks, which angs are carried respectively from the tramcs 36 and 37. The mounting of each gen of disks upon its square shaft, as well as the mounting with respect to the frames 36 and 37 are the same. Also the manner in which the raising and lowering of each ang of disks is accomplished is the same in 0th instances.

It will be apparent that the frames 36 and 37 may be varied intheir relationship with respect to the members 26 and 33 of the rigid structure or turn table upon which they are mounted.

With the members 26 and 33 remaining in v the position which is shown in Fig. 3, these frames 36 and 37 may be moved as desired by loosening and slidably adjusting bolts 45,

46 on 33 and 36, so that they occupy any desired angular position with respect to themselves, and to the chassis of the ma chine. In this way, the angle at which the disks 59 engage the ground relative to the direction in which the vehicle as a whole is moving may readily be varied.

'Vheu the disks 59 engage the ground and out the same at an angle with respect to the direction in which the vehicle is traveling, these disks then cause a cutting and turning of the soil, and thereby act as a plow of the disk ty e. As before stated, it is possible to vary t e angular engagement and b so much the amount of turning over 0 the ground by th engagement of the disks with the ground. V

In the particular position shown in Fig. 3, the disks may be used as a harrow.

The driving of the disks carried by frame 36 is accomplished through the shaft 62, and this shaft as before stated is journaled through the sleeve 54 and is also JOUI'IltLlBd at its upper end, in a sleeve 65. The shaft 62 has a driving relation with the sleeve 65 through i key or feather 66. This permits the shaft 62 to move through the sleeve 65 without destroying the driving relationship.

The: sleeve 65 1s journaled in the upper portionof the standard 50 and is rigi 1y oined with orvintegral with the gear 67.

The shaft .whichis companion to the shaft 62 and drives the gang of disks carried by the frame 37 is mounted inn. manner tohave a sliding and driving connection with a gear 67 in the same manner asthe shaft 62- withthe gear 67. .Thefifiaf 67 meshes ,with gear' 68 and the gear meshes with "a car 69. The gear 69.,is mounted-upon a s aft 70, while the gear 68 is'mounted upon a sleeve 71. To the shaft 70 there is secured a gear 72, while to the sleeve 71 there is secured a gear 3. These gears are mounted within a housing 74, and this housing at its lower end is secured upon the body or hub 30.

The driven shaft 21 extends within andis journalcd in a portion of the casing 74. This they shaft has a gear 75 mounted thereon, as shown in Fig. 5, which gear meshes with the gears 72 and 73. The purpose of the construction just explained is to form a driving connection with shaft 21, such that the disks in each gang may move with the same speed and in the same direction.

It is ouropinion that the disks operate more efiicientl'y in working upon the soil, if arerotatively driven so as to have a peripheral speed greater than would be the linea l speed of a oint on the periphery of a disk. It woul be ditlicult to state just w t ratio between the lineal speed of the m chine and the speed of the rotation of the disks should be, for it depends in a measure 11 on the character of the soil in which the disks are operating.

. Upon the upper part of that standard 50 carrying gears 67, there is pivoted an arm 76. The arm is provided with a central opening which engages with the neck or up er portion of the casing 74. At the free enr this arm 76 is provided with a curved slotted portion indicated at 77, in Fig, 2.

Upon the upper portion of the other standard 50 there is likewise pivoted an arm 78, and this arm is also provided with a portion which encircles and engages the neck and upper portion of the casing 74. The arm 78 has a bolt or stud 79 mounted thereon, which extends through the slotted portion 77 of the arm 76. The bolt permits the arms 76 and 78 to be secured together so as to form a rigid support between the standards 50 and also a support for the upper pjortion of the casing 74.

W on the frames 36 and 37 are adjusted with respect to the members 26 and 33, the bolt 79 is loosened to permit the arms 7 6 and 78 to adjust themselves in accordance with the change in angular relation effected between the frames 36- and 37. When these frames are secured in their adjusted position, the bolt 79 is again ti htcucd which holds the arms 76 and 7 8 rigidly secured to each other. i

At the rear portion of the chassis and beneath the same there is lllfillllted a guiding wheel or wheels, this being more particularly for the purpose of steering the machine when the same is running over the ground as a traction ddvice.

A frame comprising four slanting arms 80, 81, 82 and 83 are joined to the side incinbore 1 and 2 of the chassis and to illljilVQll-l;

tion of the rim. These wheels are l "Jlllllttl upon a common axle Sh and the wheels are spaced apart by means of a member having a sleeve portion H9, through which the axle 88 extends, and an upright portion 90. into which the shaft 85 extends and to which the said shaft is secured. Between the hub 84 and the member 90 there are bearing plates 91, which readily pcrnlit a rclativc turning of the member 90 with respect to the member 84.

At the upper part of the shaft 85 there is a wheel 92. 1 round this wheel there. is a. cable 93 which upon passing from the wheel engages with guide rollers 9t and extends parallel with the chassis of the machine toward the front portion thereof.

At, the forward portion of the chassis there is mounted a tubular elcment- 5 as shown in Fig. 1, the same being journalcd in a suitable manner upon the chassis frame. Tnis tubular member at its upper ortion is provided with a hand wheel 96.

Within the tubular element 95 there is a shaft 97 which is provided with a hand wheel 98 above the hand wheel 96.

The lower p rtion of the tubular element 95 is provided with a small drum 99 and upon the lower end of the shalt 97 there is a drum 100. T he cable 93 which cooperates with the wheel 92 is suitably secured upon the drum 100 so that the turning of the wheel 98 causes the cable to be appro priately moved so as to effect a turning of the wheels 86 and 87 in a direction to accomplish the steering of the machine.

The circular member 33 which forms a part of the turning table upon which the ungs of disks are carried is preferably ormed with an external channel in which is laid a cable 101, which cable is suitably secured to the member 33 and also cooperates with the drum 99 upon the tubular element 95. Therefore a turning of the hand wheel 96 in a proper direction will elfect a corresponding turning, of the turn table. and the gangs of disks carried thereby.

The machine when in use as a harrow or plow may be guided very elfectively by manipulation the turn table by which the gangs of disks are carried and this control is much quicker and more ell'cctivc than would be the control effected by the manipulation of the wheels 86 and 87, that is to say, when the disks are in use as a plow or barrow.

However, when the machine is merely acting as a. traction device, or being propelled from place to place, the disks not being: in service, it isv then necessary to provide a. means for steering the rear wheels 8 and 87 which is accomplished in the manner heretofoic. set forth.

Each ofi lhc wheels oh, .which are upon theslml ls that. gov-'orn the lilting and lower of the hand wheel which controls y roller accomplishes a rolling if the plowed ing of the gangs of disks, cooperates with a cable 102, which cable extends to a forward portion of the chassis whcre it engages with a drum carried by a hand wheel 103, the hand wheel being preferably mount ed upon the portion of the chassis which is adjacent to the various devices for opcrat ing the various instrumentalities tlr-i tulutt'il with the machine. It will be. apparent that the operation of the wheel 10:; results in the raising and lowering of each gang oi disks as a unit.

Mounted upon the chassis adjacent to the various operating devices for the dillcreul instrmnentalitics of the machine is a seat 104, which is to be occupied by the operator of the machine, and as will be apparent from the description of the machine and the illustration of the drawings, it is the inteir tion to locate the various operating tlt'\'lt't:- in such manner that they may be conveniently operated by the driver of the machine.

It will be perfectly apparent that the machine ma} bc provider with appropriate bake mechanism.=and while various forms of brake machanism may be. used. it may be pointed out in a general way that suitable foot, lcvcl's cooperate with rod:-., \l1ich r ds cooperate with levers such as shown at 109 ca rricd upon a shaft 111.) journaled upon the side portions 1 and of the chassis. The shaft 110 is provided with a suitable. rod connection 111 which operates the brake mechanism represented at 112 in Fig. 1, upon a drum 113 which is associated with the shaft 10. A

it. will be understood that there is a similar drum and brake mechanism associated with the shaft 9. 'lhcreforc, it will be apparent that. it. is possible to apply braking force to either the shaft 9 or shaft 10, singly or both together.

it will be. noticed that the, traction device :i.--Hlllii(H the form of a roller extending across the width of the machine. This roller is made in two parts, as heretofore. explained, but the parts are, so related to each other as to give in cll'cct a substantially continuous roller.

When the. machine is in ustgl the broad or hurl-owed soil. which tends to pulvcrize or work up the soil into a desirable condition for planting. i i

In fact, the machine may be used for the purpose of rolling alone. by merely elevating the disks to such a position that they will notcontact. with the ground, or they may be omitted or removed from the machine. Under such condil ions, the machine is guided or v teered by the rear wheel, while the traction rollcr pcrforn'is its function of breaking up and pulvcrizing the previouslyplowed or harrowcd soil.

The auxiliary frame upon which the tree operative connections tion roller-is mounted forms a-very suitable and efficient means for mounting the roller, but obviously other means of mounting the roller with respect to the chassis may be used, and still be within the scope of this invention.
